Segway I170

Long time member first time poster..

I have a Segway I170 with NI-MH batteries..
Due to an error condition I ignored my segway for a number of years.
So with our current worldy status I started investigating things with it again.
Batteries where in this status..

After leaving it charging over night...

Battery-1 Left-side voltage > 43
Battery-1 Right-side voltage > 43

Battery-2 Left-side voltage between 36 and 39
Battery-2 Right-side voltage between 36 and 39

Startup status....provided the 'unlocated fault' according to the Reference Manual.

Switching batteries made no change....

So with some discussion I was made to believe that one of my batteries may be the problem. So I opened it up (Battery-2) and with a Heat gun and patience the battery and board slid out via gravity...

Inspection of the 6 10-battery cells... showed lower voltage on all but 2.
So I inspected the individual cells and found 8 bad cells 0volts or less than 1 volt. So I proceeded to change those 8 cells.

Battery-2 Left-side voltage > 44
Battery-2 Right-side voltage > 44

so the Startup status has not changed...

So with Web and forum investigation I was curious if I had a HandleBar or CSB issue or cable issue.

Last night I read that some people suggested over time to switch the CU's .. So I proceeded to do this.

Startup status now is startup attempt is quicker.. but goes directly to a Full Circle Error with wrench...

So this is where I am .. Hopefully I didn't forget anything..

Hope someone out there has additional ideas..
